I think header with name of the site should be more readable so people could remember your name much easier. Everything else looks good to me . Back review appreciated at http://forums.digitalpoint.com/showthread.php?t=839365
The only thing you should change is the header. Other than that it looks really nice. Great selections of wallpapers too! ^_^
Yes, the text in the header is hard to read - also, can you do something to fill the empty space toward the bottom of the outside columns? That would make it more balanced ... good luck!
The header needs work and the site may look better if the ads were placed in the left or right column instead of the middle.
